Malcolm Beare of South Australia patented and developed a remarkable engine which has been described as a cross between a twostroke and a fourstroke - hence, sixstroke. The machine had numerous qualities including far fewer moving parts (no poppet valves) and simply staggering torque. A video shows Malcolm astride a single-cylinder version with the front wheel planted against an obstacle, spinning the back tyre at what seems like very low rpm. The Ducati version was equally impressive.
A con-man took control of the company and stole the patents and the investor's funds. Allegedly.
